PoESP32

SKU:U138

Description

PoESP32 Unit is an ESP32 Ethernet Unit supports PoE (Power Over Ethernet). This module adopts ESP32 as built-in MAC, and IP101G as physical layer transceiver. Default firmware with ESP-AT, supports TCP,MQTT, HTTP protocols. It can connect to server with simple AT commands through serial port, achieving data transmission and remote control functions. This module simplify wiring and saves labor cost with PoE power supply, and It reserves the ability for secondary development to meet your requirement.
